Capacitive passenger detection utilizing dielectric dispersion in human tissues

Vehicle Occupant Head Position Quantification Using an Array of Capacitive Proximity Sensors

“…Specifically, George et al [15] presented a capacitive sensor design with applications in airbag systems. Capacitive sensing achieved by placing several capacitive sensors in different locations in the passenger compartment for the purpose of occupancy detection were reported by George et al [15], [16] and by Satz et al [17].…”

Capacitive seat sensors for multiple occupancy detection using a low-cost setup

“…A number of studies have therefore gone into capacitive sensors for seat occupancy detection with several prototypes developed. Most of these occupancy detection sensors are developed for smart airbag systems [10], [11], [12] and to monitor drivers' vital signs [13], [14]. The focus of the above mentioned sensors are performance (fast response time) and high sensitivity.…”

Capacitive Sensors

“…Pavlov et al [48] describe a configuration with small electrodes located in a doorway, giving a capacitance change of a few tenths pF when a person passes. [50]. George et al [49] discuss a capacitive method to detect the presence of a person on a car seat.…”
